The second memory array deck differs from the first memory array deck in one or more operating characteristics, in pitch, and/or in one or more structural parameters; with the structural parameters including different materials and/or different thicknesses of materials. Some embodiments include a construction having a first series and a third series of access/sense lines extending along a first direction, and a second series of access/sense lines between the first and third series and extending along a second direction which crosses the first direction. First memory cells are between the first and second series of access/sense lines and arranged in a first memory array deck.
